Cyberbullying is a form of online aggression between peers, the prevalence of which varies from 10% to 40% according to studies in different countries. A large share of the scientific literature on cyberbullying tends to individualize and medicalize the causes of the violence, without understanding the context in which…

The calculation of a study's required sample size is one of the most important aspects of the validity of an epidemiological study. Logistic regression often is used in modelling in epidemiology. A simplified method to calculate the sample size for the multiple logistic-regression model was proposed by Hsieh et al. [St…

: An estimated 21% to 58.8% of U.S. college student populations experience food insecurity (FI)-that is, limited or uncertain access to adequate food. Ameliorating this FI requires the involvement of college administrations. This study seeks to explore campus administrators' understanding of-and support for-students wh…

Generic ophthalmic drug product development is challenging, and innovative methodologies to complement traditional bioequivalence (BE) studies for BE assessment are desirable to promote their evaluation. Ocular physiologically based pharmacokinetic (PBPK) models can provide insight into drug partitioning in eye tissues…

BACKGROUND/OBJECTIVE: The development of simple postural stability tests that relate to performance of activities of daily living (ADL) and can be quickly performed in a clinical setting may assist clinicians in determining appropriate wheelchair configurations and postural supports in an efficient manner. The study's…

We examine alcohol use in conjunction with ecstasy use and risk-taking behaviors among regular ecstasy users in every capital city in Australia. Data on drug use and risks were collected in 2004 from a national sample of 852 regular ecstasy users (persons who had used ecstasy at least monthly in the preceding 6 months)…

Further analysis of a previously reported transformational leadership study indicated that the study's 81 excellent nurse executives can be further delineated into four groups based on the difference between the scores of nurse executives and staff for transformational and transactional leadership. Part 1 reports quest…

The role of psychosocial factors in peptic ulcer remains controversial. We have investigated the relationship between socioeconomic status, concrete stressors, and ulcers in a longitudinally followed, population-based cohort, taking confounding risk factors into account. A total of 6,928 adults completed the Alameda Co…

In research involving human subjects, large participation payments often are deemed undesirable because they may provide 'undue inducement' for potential participants to expose themselves to risk. However, although large incentives may encourage participation, they also may signal the riskiness of a study's procedures.…

The present study empirically confabulates the authenticity of the "resource curse hypothesis" in selected emerging nations. Furthermore, we also assessed the interconnections of three essential economic indicators with financial development, i.e., human development, political stability, and gross domestic product. To…

INTRODUCTION: Epstein-Barr virus (EBV), a double-stranded DNA virus, has 2 phases of lytic and latent infection in host cells. After infecting B lymphocytes, EBV becomes persistent in these cells. In healthy individuals, T lymphocytes play a key role in killing EBV-infected B cells. Statistical studies have shown that…

This study's hypothesis is that human immunodeficiency virus-infected patients in the inner city (predominantly injection drug users and ethnic minorities) do not take highly active antiretroviral therapy (HAART) as prescribed and that nonadherence leads to virologic failure. A prospective, observational, 3-month study…

Responsiveness defines the prompt, contingent, and appropriate reactions parents display to their children in the context of everyday exchanges. Maternal responsiveness occupies a theoretically central position in developmental science and possesses meaningful predictive validity over diverse domains of children's deve…

While there has been considerable inquiry into how religion may help Christians deal with stressful life events (SLEs), only limited research has been conducted on the impact SLEs might have on religion. This study's purpose was to provide an in-depth analysis of this relationship in a sample of highly religious Christ…

This research aimed to investigate the mediating function of Green Employee Empowerment (GEE) in the relationship between Green Human Resource Management practices (GHRM) and the environmental performance of small and medium-sized enterprises (SMEs) in Ghana, drawing on the Ability-Motivation-Opportunity (AMO) theory.…

Chronic non-communicable diseases represent a major public health problem, requiring more effective investigation and control by government agencies. The aim of this study was to correlate the mortality rate for oral cancer in Brazilian State capitals from 1998 to 2002 with socioeconomic factors collected in the 2000 c…

This chapter focuses on the development and evaluation of prediction models for heart failure using machine learning techniques. By analyzing patient characteristics and applying algorithms such as random forest, gradient boosting, and others, highly accurate predictions were achieved. The findings demonstrate that mac…

BACKGROUND: The emergency rescue ability of firefighters is particularly important in the event of major disasters or accidents. Therefore, an assessment of the firefighter-training effectiveness is necessary. OBJECTIVE: This paper aims to achieve a scientific and effective assessment of the firefighter-training effec…

Venous thromboembolism (VTE) occurs at an increased incidence in cancer patients. A cancer-related hypercoagulable state has been considered to play role in this phenomenon. Preclinical data suggest an association between tumor expression of MET proto-oncogene (MET) and a hypercoagulable state, resulting in VTE. We inv…

PURPOSE: The effect of infant formulas sweetened or not with sucrose on primary enamel demineralization and dental biofilm is not known. This study's purpose was to evaluate the effect of infant formula and sucrose association on demineralization of primary enamel and dental biofilm formed. METHODS: A cross-over, spli…
